Abstract

The article presents the results of studies of the influence of wind load on the dynamic characteristics of Solar Power Station (SPS) tracking systems for the Sun with two-coordinate electromechanical actuators in the conditions of the Karakum desert. The load on the actuator under the action of the wind showed that when using a stepper motor of the brand (ShD-5D), which has a nominal moment of 0.4 N·m, in the SPS-0.5 installation at a wind speed of 20m/s, the moment from the action of the wind load in the system of movement along the azimuth exceeds the maximum moment of the SD by 1.2 times, and at a speed of 25m/s- by 1.9 times. Regression equations are compiled and the correlation coefficient is determined. The determination coefficient confirmed that the impact of wind load on the dynamic characteristics of electromechanical systems in terms of angle and azimuth is 86.04%, and the remaining 13.96% is the influence of the engine drive shaft at the moment of inertia of the frame with SPS and other unaccounted for factors.
